Exhaust/emission question
My oil filter gasket was leaking as well as my oil cooler O-ring, god knows why a few weeks ago, and all the oil traveled down to my o2 sensor above my cat. Oil issue fixed, but I got 2 check engine light codes saying my exhaust/emissions system is failing (P420, and another i cant quite remember)... Would that be from all the oil dripping onto my exhaust/cat and making smoke???
Does anyone know what a stock h22a can run with auto tranny for 1/4 mile???

Re: Exhaust/emission question (Seroga415)
P0420 is catalytic converter efficiency code. it thinks that the cat is not working, most likely due to oil ruining the O2 sensor
